ya i take light 10mg at 9 pm and have zoning out problems at 4pm to 7pm the next day if i'm out in school and i start frowning because i turn into an emotionless robot but thats quite light at 10mg... the weight gain was horrible i went up from 138 to 204 pounds now i'm down again at around 140 almost normal weight just a fraction more and i'm fine.... but took quite an effort and psychological toll... i'm fasting 20 hours most days... and i'm semi-vegan i jog a lot sometimes 15km and lift weights just to keep the weight down, coffee helps with the zoning out though... the sleepiness took quite long to wear off... almost been 5 years then only it started to wear down, not too drowsy nowadays and i can drive easily... but i'm currently diagnosed with hypomania so i don't know why i'm taking it... lol
